A couple weeks ago I was having a constant fluttering feeling in my chest. When I put my hands over my heart it seemed to be skipping. I asked my boyfriend to do the same..and he also said it seemed to be skipping. I felt very strange and I couldn't sleep even though I was really tired. As a child I could never keep up with the other children. Even the smallest amount of activity tires me out. And no I am not fat. I am a bit underweight. Now I don't really feel the fluttering but I've been getting dull pains in my heart at random times. I'm 18 it seems I am a bit young to be having heart problems..I also am uninsured and can not afford a doctor. Should I be worried?
